Pullswitch
Open Conveyor Pull Cord Safety Stop Switch
APPLICATION
The Pullswitch is a failsafe taut wire emergency pull cord stop
switch for open conveyors.
METHOD OF OPERATION
PVC coated steel pull wire and pigtails connect between the
switches to provide easy installation and continuous emergency
stop access along the length of the entire conveyor. The unique
open curled design of the pigtail allows the pull wire to be
installed or removed without disconnecting the entire
assembly. Pullswitches can be installed at 200 ft.
intervals, reducing overall system cost. Quick location
of a tripped switch is provided by a cat’s eye reflector or optional
flag indicator, and the tripped signal can be wired back to the
motor starter and an alarm panel or PLC.
The Pullswitch is a taut wire device, so if wire tension is lost the
unit will trip. This design provides a secondary level of safety
protection if the pull wire is damaged, or becomes slack.
ATEX Approved
Versions Available
The Pullswitch has an IP65 / NEMA 4, 4X, 9 rated enclosure
made from polycarbonate with stainless steel plates, making the
housing corrosion resistant and weatherproof. A total of six
independent changeover contacts inside the Pullswitch offer
flexible operation and control. Two independent cam operated
switches with snap action mechanical operation are provided for
conveyor shutdown, and four additional micro-switches signal a
slack wire alarm.
